摘要:
A fluorescent structure for a light-emitting package includes a first fluorescent layer and a second fluorescent layer covering the first fluorescent layer. The first fluorescent layer includes first fluorescent strips, and defines first transparent regions between the first fluorescent strips. The second fluorescent layer includes second fluorescent strips, and defines second transparent regions between the second fluorescent strips. A method for forming the fluorescent structure and a light-emitting diode package using the fluorescent structure are also provided.

A light-emitting element package includes a package member for encapsulating a light-emitting element. A plurality of photonic crystal patterns is formed on the package member. A distribution density of the photonic crystal patterns corresponds to light distribution of the light-emitting element. Each photonic crystal pattern consists of a plurality of photonic crystals.

An LED package includes a substrate, an LED die, and an encapsulating layer. The LED die is arranged on the substrate. The encapsulating layer covers the LED die and at least a part of the substrate. The encapsulating layer includes a light dispersing element. A light scattering intensity of the light dispersing element is proportional to the light intensity of light generated by the LED die and illuminated at the encapsulating layer. A luminance at a center of the LED package is substantially identical to that at a circumference of the LED package.

A light emitting diode comprises a sheet-like package body, a barricade, a light emitting diode die, and fluorescent filler. The sheet-like package body has a die-bonding region. The barricade is a transparent wall that is disposed on the die-bonding region, and is integrated with the sheet-like package body or is adhered to sheet-like package body. The light emitting diode die is disposed on the region enclosed by the barricade, and the fluorescent filler is also filled into the region and surrounds the light emitting diode die. The light emitting diode and the method for packaging the light emitting diode can improve the uniformity and efficiency of the outputting light emitted from the light emitting diode, and the loss of the outputted light is reduced.
